Free Wisconsin Gun / Firearm Bill of Sale
Wisconsin is a permissive-firearms state: no permit-to-purchase, no waiting period, no state registry, no assault-weapons ban, and no magazine-capacity limit. Private-party transfers between Wisconsin residents who are not prohibited persons require no background check under state law (federal law still bars knowingly transferring to a prohibited person). FFL handgun transfers run a Wisconsin DOJ Firearms Database check; long-gun transfers run NICS only. Concealed carry still requires a Wisconsin CCW permit — Wisconsin has not adopted constitutional carry.

Wisconsin Gun / Firearm Bill of Sale — What You Need to Know
Sales Tax Details
Private-party firearm sales in Wisconsin between non-dealers are generally not subject to state sales tax. Sales through a licensed FFL dealer are subject to 5% state sales tax plus 0.5% county tax. Wisconsin does not impose a separate firearms or ammunition excise tax beyond the federal 10–11% Pittman-Robertson excise tax (paid by manufacturers).
Inspection Requirements
Wisconsin private-party firearm transfers do not require a state background check. FFL dealer transfers run a state DOJ Firearms Database check (Wisconsin's state-level system) plus the federal NICS check, and the DOJ handgun check can take up to five business days — the dealer may not hand over the handgun until DOJ approves. Wisconsin eliminated the 48-hour handgun waiting period in 2015. Long-gun (rifle, shotgun) transfers at FFLs require only NICS, not the state DOJ check.
Wisconsin Gun / Firearm Sale — Step-by-Step Checklist
- Verify the buyer is a Wisconsin resident, age 18+ (federal law bars handgun transfers to anyone under 18; the age-21 handgun rule applies only to dealers), and not a prohibited person under federal/state law
- Bill of sale: make, model, caliber, serial number, buyer name and address, seller name and address, and date
- Both parties keep signed copies for their records (no state filing required)
- Optional but recommended: ask for the buyer's Wisconsin driver's license or CCW permit and note the number
- For interstate sales: federal law requires the transfer go through an FFL in the buyer's home state
- For NFA items, check ATF's current rules at atf.gov/nfa before any transfer. Machine guns still need ATF approval and the $200 tax, and Wisconsin law also restricts them (Wis. Stat. § 941.26). Since October 9, 2026, ATF no longer requires approval or registration for suppressors and short-barreled rifles and shotguns (their tax has been $0 since January 1, 2026). But in Wisconsin, having a suppressor is a Class H felony unless you have complied with the federal licensing and registration rules (§ 941.298), and the same goes for short-barreled rifles and shotguns unless they are federally registered or lawful under federal law (§ 941.28). ATF changed its policy, not the federal law, so an unregistered one may still be a crime in Wisconsin. Ask a Wisconsin firearms attorney before buying or selling one.
- Store the bill of sale safely — your only proof if the firearm is later recovered or used in a crime
Common Pitfalls
- Knowingly transferring to a prohibited person (felon, domestic abuser, drug user, etc.) — this is a federal felony regardless of Wisconsin's permissive laws
- Selling any firearm (not just a handgun) to an out-of-state buyer face-to-face — federal law requires an FFL transfer in the buyer's home state
- Assuming Wisconsin has constitutional carry — it does not. Concealed carry requires a Wisconsin CCW license (open carry of long guns/handguns is generally legal without a permit)
- Skipping the serial number on the bill of sale — without it, the document doesn't prove which specific firearm changed hands
- Confusing Wisconsin's eliminated 48-hour handgun wait (gone since 2015) with the federal NICS delay that can still happen at an FFL
Pro Tip
Wisconsin firearm law is permissive but not lawless: no permit, no wait, no registry — and no state background check on private transfers — but federal prohibited-person rules and CCW licensing for concealed carry still apply. A clean bill of sale with serial number is your only paper trail.
